Let your goodness, O God, bind my heart with a chain
to you! Seal my will to yours with an unbreakable application of your eternal covenant…. Keep me!
Preserve me! Defeat every rising rebellion!
Overcome every niggling doubt! Deliver from every destructive temptation! Nullify every fatal allurement! Expose every demonic deception! Tear down every arrogant argument! Shape me! Incline me! Hold me! Master me! Do whatever you must do to keep me trusting you and fearing you till Jesus comes or calls.
